This SparkFun Qwiic MicroPressure Sensor is a small breakout board featuring the Honeywell 25psi piezoresistive silicon pressure sensor. This MicroPressure Sensor is capable of a pressure sensing range of 60mbar to 2.5bar in an easy to read 24 bit digital I2C output. The Sensor can be calibrated and compensated over a specific temperature range for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). This is one powerful little sensor to have as part of your project, coupled with low-power consumption and qwiic ports, it’s also very adaptable!
Each Qwiic MicroPressure Sensor has a calibrated pressure sensing range from 1-25psi and a power consumption rate as low as 0.01mW typ. average power, 1Hz measurement frequency for ultimate portability. Used in multiple medical (blood pressure monitoring, negative pressure wound therapy), industrial (air braking systems, gas and water meters), and consumer uses (coffee machines, humidifiers, air beds, washing machines, dishwashers), the SparkFun Qwiic MicroPressure Sensor is a great addition to the SparkFun Qwiic ecosystem!
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
